The invention provides a method for treating nitrate wastewater through a three-dimensional electrode biological membrane, and belongs to the technical field of nitrate wastewater treatment. The method comprises the following steps: constructing a cylindrical three-dimensional electrode method bio-membrane reactor by taking activated carbon as a substrate, taking a cylindrical shape enclosed by a plurality of graphite rods as a cathode and taking a middle graphite rod as an anode; the reactor cathode generates H2 under the action of impressed current, autotrophic hydrogen type denitrifying bacteria grow and breed depending on H2 and are attached to the surface of a cathode graphite rod to form a biological membrane, nitrate nitrogen in water can be diffused into the biological membrane, and the biological membrane on the surface of the cathode graphite rod utilizes the generated H2 to reduce the nitrate nitrogen; cO2 is generated at the anode of the reactor and is further converted into carbonic acid, bicarbonate radicals and carbonate radicals, and a carbon source required by growth and reproduction is provided for the autotrophic hydrogen type denitrifying bacteria. According to the three-dimensional electrode bio-membrane reactor, a filling material is added in a two-dimensional reactor structure to serve as a supplementary electrode, and stronger wastewater treatment capacity is brought by a larger surface area.

A photosensitive power supply module supplies power to an electric telescopic rod when monitoring that the illumination intensity on the water surface reaches a preset threshold value, the electric telescopic rod stretches and retracts in a reciprocating mode to drive artificial aquatic plants to periodically immerse into the water surface or emerge from the water surface during power supply, and in the immersion process, the electric telescopic rod drives the artificial aquatic plants to float out of the water surface; the surface of the artificial aquatic plant adsorbs pollutants in a water area, and in the floating process, the photocatalytic composite film can perform photocatalytic decontamination on the adsorbed pollutants under natural illumination; the photosensitive power supply module supplies power to the light-emitting assembly when monitoring that the illumination intensity on the water surface is lower than a preset threshold value, the electric telescopic rod is kept in an extension or compression state to drive the artificial aquatic plants to be immersed into the water surface, and the light-emitting assembly conducts close-range illumination on the photocatalytic composite film. The photocatalytic composite film can perform photocatalytic removal on pollutants in water under the condition of no light or weak light, so that all-day and all-time effective photocatalytic decontamination is realized.

The invention relates to an efficient water purification quartz sand filtering method, and belongs to the technical field of quartz sand filtering. Comprising the following steps: S1, feeding circulating cooling water into a filtering tank; s2, adding potassium permanganate and ferrite into the circulating cooling water in the filtering tank, uniformly mixing, and carrying out a flocculation reaction to form a floc; and S3, sequentially filtering the water flowing out of the filtering tank through quartz sand filtering layers with different particle sizes in the filter. Before a water source is filtered, potassium permanganate and ferrite are used for pretreatment, natural organic matter can be effectively removed, meanwhile, quartz sand with different particle sizes can filter the water source stage by stage, and suspended solids, microorganisms and slime in circulating cooling water are effectively controlled to be filtered and intercepted; the water purification efficiency and the water purification effect are effectively improved.
